Systemic insecticides for Zimmerman Moth contro #371072

Asked October 18, 2016, 6:36 PM EDT

Would it be advantageous to inject Imadacloprid or DySiston into the infected Pines in lieu of applying topical insecticides.  We were called to look at approximately 150 8"- 14" Pines where these Moths are residing.

Expert Response

Insecticides containing Bifenthrin, Carbaryl or Permethrin are the only trunk sprays proven to protect pines.  These should be applied until they runoff not just misting the tree. They should be applied into fissures and cracks and around the base of the trunk, including the entire tree using a hydraulic sprayer with at least 250 psi for small trees. Each tree needs to be sprayed in this manner not just in an area around the perimeter.  There is no mention made of injection of insecticides.
